TWISTING-TUBE FOR TWISTING FIBROUS MATERIAL INTO THREADS.

SPECIFICATION forming part of Letters Patent No. 552,657, dated January *7, 1 896.

Application filed February l, 1895. Serial No. 537,030. (No model.)

To all whom, it may concern:

Be it known that we, JAMES WV. BEDALE and JOSEPH G. BEDALE, citizens of the United States, residing at the city of Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful lmprovements in Twisting-Tubes for Twisting Fibrous Material into Threads; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

Our invention consists in the improvement in twisting-tubes for twisting fibrous material into threads hereinafter set forth and described and illustrated in the accompanying drawings, in which- Figure l is a view in elevation of our improved twisting-tube with parts of the mechanism connected therewith in section. Fig. 2 is a central longitudinal section of our improved twisting-tube. Fig. 3 is a perspective view of the adjustable central section of the same.

Heretofore twisting -tubes for twisting fibrous material into threads have usually been made so as to twist a given-sized thread, and without any means of adjusting them so as to twist threads of different sizes. Again, there has been no such construction that we are aware of which provides for taking lup the wear of the opening at the apex of the twisting-tube, neither have they been so constructed that the thread may be made with any desired twist. These difficulties we have overcome by making the tube so that the opening in the apex thereof may be'varied in size as desired, as by longitudinally slotting the central section thereof we can so adjust it as to vary the size of the thread made as may sections B and C, as is clearly shown in Fig. 2. The outer section B is provided with journals b b', which operate in bearings a a on the machine-frame A. It is also provided with a central driving-pulley h2, over which a belt D operates to drive it in the usual manner.

rlhe central part of the section B is bored out of equal size and internally screw-threaded for nearly two-thirds of its length from the rear end thereof, and the remainder of its length is bored out conically, so as to leave an opening d in the outer end or apex of the section B of approximately one-third the diameter of the conical portion of the bore at its rear end.

The inner section C of the twisting-tube is made of equal size and screw-threaded on its periphery for about one-third of its length from its rear end, the screw-thread thereon fitting the internal screw-thread in the rear portion of the outer section B. The 4rear end of the section O is also provided with grooves c to receive a wrench for screwing the section G into place in the section B. The periphery of the front end C' of the section C is turned off so as to coincide nearly with the conical bore of the front end of the section B. Through the center of the section C is bored a conical opening E, which extends from the rear end thereof to within, say, threeeighths of an inch of the front end thereof, and from that point to the front end of the section O there is bored a small opening c of equal size fr om end to end. The front end of the section O is provided, preferably, with four radial slits or kerfs f, as illustrated in Figs. 2 and 3, which extend from the front end back nearly half of the length of the section O. A portion of the central part of the periphery of the section C, between the front end of the screw-threaded part thereof and the conical part O', is also cut away, as illustrated in Figs. 2 and 3, which allows the ends of the sections of the conical part O of the section C to be sprung together as the section C is screwed into the section B, and the spring thereof brings them back to place when the section Gis moved back, so that by screwing the section C in or out of the section B the size of the opening e in the front end of the section C may be reduced or enlarged as desired. The slits or kerfs falso operate to engage the iiber H during its passage through the twisting-tube and twist it into a thread h, which is drawn away from the front end of the twisting-tube by the rolls A A', as illustrated in Fig. l, the size oi' this thread being Varied by adjusting the inner section C Within the outer section B of the twisting-tube, as hereinbefore described.

Having thus fully described our invention, so as to enable others to construct and operate the same, what we claim as new, and desire to secure byLetters Patent of the United States, is-

The combination in a twisting tube for twisting fibrous material, of an outer section having a driving pulley thereon, journals at each side of said pulley, an opening therethrough internally screw threaded at its inner end and conically bored at its outer end, and an inner section having the periphery oi' its outer end conical, and its inner end peripherally screw threaded to iit the internal screw threaded portion of the outer section, and a conical central opening therein extending from its rear end to its front end, and radial slits or kerfs in its outer or conical end, substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.

JAMES W. BEDALE. JOSEPH G. BEDALE.
